PUMP.

SPECIFICATION forming part of Letters Patent No. 287,461, dated October 30,1883.

I Application filed January 5, 1883., (No model.)

T dll whom, it nfl/ay concern/ Be it known that I, PARnoN T. PERxrNs, of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Pumps, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact descrip-v tion'.

This invention lconsists in a novel construction of a rotary pump exerting a centripetal force on the water to be drawn or propelled; and it also consists in certain auxiliary devices connected with said pump for transmitting thereto the requisite power, and for protecting it against frost, all as hereinafter more fully described, and set forth in the claims.

In the annexed drawings, Figure lis an elevation of my improved pump, with portions broken away to betterillustrate the connections of the stationary discharge-pipewiththerotary pipe. Fig. 2 is a plan View of the pump-case with the cover thereof removed andthe pump mechanism shown by dotted lines, to illustrate y the construction of the interior bottom of the case. Figs. 3 and 4t are transverse sections taken on lines x :v and y y, respectively, in Fig. 2. Fig. 5 is an inverted plan View of the rotary hub and its buckets. Fig. 6 is a horizontal transverse section of the same. Fig. 7 is' a detail view of the automatic vent, and Fig. 8 is a'detail View of the coupling of the stationary discharge-pipe with the rotary eduction-pipe.

E represents a circular metallic case joined with another smaller circular metallic case, F,

which is on thesame plane, and has its periphery intersecting that of the case E, so that the interiors of the two cases communicate with each other. tally, either submerged in the water to be pumped or in an elevated position, as illustrated in Fig. l of the drawings, to which latter position the following Ydescription will be chiefly conned. rIhe interior of the case E, which constitutes the main case or shell ofthe pump, is provided in the center of the bottom with asocket or step, D, in which is journaled a gudgeon, kD', iixed to the under side of a ro-v tary hub, G, the diameter of which is consid- These cases are placed horizon.

erably smaller than that of the case, so as to leave around said hub an annular channel, U. The two ends or top and bottom faces of the hub G are each provided with a circumferential rim or flange, c, which is tted water-tight in a corresponding annular groove, b, inthe adjacent face of the case E. In the vicinity of the junction of the two cases E and F the bottom of the case Eis provided with theinduction-port H, arranged in the annular waterpassage U, formed around thehub G, as before described. Said induction-port is to be provided with a suitable valve, i', in case the pumpchamber is arranged above the surface of the water.` diametrical channels I I, and with an axial channel, K, extending from the radial channels through the top of the hub. The radial channels I communicate with hollow arms or buckets A A, which are fitted closely in the annular water-channel U, and are firmly secured to the periphery of the hub, either by casting them thereon or by providing the buckets with a screw-threaded nipple and screwing them into theychannels I of the hub, screwthreaded correspondingly for that purpose, as illustrated in Figs. 4L and of the drawings.

In order to insure a perfectly water-tight iit of the buckets on the interior of the case E, I face the mouth or open end of the bucket with a rubber orleather packing-disk, M, secured l thereto by a brass plate, L, placed over the said disk and fastened by bolts tapped in the face of the bucket, said plate having a central opening .for the entrance of water into the bucket. An inwardly-opening valve, p, is placed over the mouth of the bucket-said valve may be formed in the usual mannerby making in the packing-disk M' incisions extending around three sides of the mouth of the buckets, and in suchl a manner as to allow the released portion of the disk tolap onto the outer plate, L,which projects somewhat over the edge of said mouth.

In the supplemental case F is arotary gate, B, consisting of wings or plates extending radially from va hub pivoted in the center of the case. Said `gate-plates are fitted closely to the interior of the case, and have secured to their back a packing-disk, o, by means of a plate placed over said disk and bolted to the gate IOO plates or wings, as illustrated by dotted lines in Fig. 2`of the drawings. The packing-disks projecting at the edges of theywings insure a water-tight joint around the same.

To the under side of the case F is attached one end of a spring-bar, N, the free end of which reaches under the main case E, and is provided thereat with two pins, c c', which project through the bottom of the case E, so as to bring one of said pins, c, in the path of the gate-plates B in the vicinity of the induction-port H. The other pin, c', comes into an annular cavity, d, which is formed on the under side of the hub G, between the peripheral ilange a and central gudgeon, D, thereof. In the aforesaid annular cavity d the hub G is provided with cams or beveled bosses e, arranged in such positions in relation to the bucket A that when the hub G is rotated they cam e will encounter the protruding pin c', and thereby push both pins c c out ofthe case in time to liberate the gate-wing B, and allow the same and the bucket A to freely advance intheir respective cases. The operation of the pump is as Vfollows: The hub G being rotated in the direction toward which the mouth of the bucket faces, and as indicated by arrows in the annexed drawings, creates a vacuum at the rear of the bucket, and thus draws the water through the induction-port H. The succeeding bucket A drives the water around the annular channel U of the case E, and the pressure of the propelled water throws one of the gate-wings B against the protruding pin c, which holds said wing, and thereby presents a barrier to the passage of the water directly back of `the induction-port H. The water thus arrested is forced into the bucket or hollow arm of the hub G, and through the radial channel I and axial channel K thereof, from which latter it enters the exit or discharge pipe P, connected therewith, as hereinafter described. In the close approach of the bucket to the gate the cam eencounters the pin c', and thereby releases the gate B, and allows the bucket to proceed and repeat its operation on the water, which has in the meantime entered through the induction-port H. As one gate-wing is released, another is swung around and arrested by the protruding in c in time to stop the flow of water propelled by the bucket following the one aforesaid.

It will be` observed that in the operation 'of the pump the supplemental chamber or case F becomes filled with water, and the gatewings are thus relieved of the shock incident to collision with the stop-pin c.

The described pump mechanism receives its motion by the following instrumentalities: The discharge-pipe P is made to serveas the driving-shaft, and is therefore firmly secured to the hub G by screwing the end of said pipe into the axial channel K of the hub, which is screw threaded for that purpose. When the pump is applied to a well, as illustrated in Fig. l of the drawings, the pipe P is extended up above the top of the well, where it is jonrnaled in a suitable box secured to a suitable frame, Z. A miter-gear, h, attached to the end of the pipe P, meshes -in a miter-pinion, t', attached to ahorizontal shaft, k,which is mounted in suitable bearings on the frame Z, and is provided either with a crank, lm, or other suitable means for turning said shaft k. By means of bearings f f, attached to a post or other support fastened on the side of the well, the pipe P is steadied at different points of its length. To protect the pipe P from frost, said pipe is provided at a proper distance below the top of the well with a coupling, T, in the form of a sleeve, having intermediately screw-threaded ends qq, in which are screwed the ends of the lower and upper sections, respectively, of the pipe P. VBetween the ends of said pipe-sections the interior of the coupling is provided with a shoulder, r, and upon this rests the stationary dischargepipe P', which is provided with a collar or ilange, u, on its lower end. Upon the collar is placed ter is applied an anti-friction metal ring, s. Theupper section of the rotary pipe P being screwed downY to bear with its end on the ring s eifectually prevents the water from passing upward between the two pipes P P', and compels the tionary pipe, which projects above the upper part of the rotary pipe P, and is provided with the spout S, and, if desired, with an airchamber, V.

In order to guard against frost in the dis-v charge-pipe P, I employ an automatic vent consisting of a tubular arm or nipple, n, screwed into the coupling T at a point at or above the end of the lower section of the pipe P and below the lower end of the stationary pipe P. On the outer end of said nipple n is hinged a gravitating arm, R,'which has its hinged end across the channel o of thenipple, and has on the side facing said channel an excision, o, extending downward from the channel o of the nipple, and thus forming a vertical outlet, o', for the water from the channel o when the arm B is at rest or in its normal pendent position, as illustrated by full lines in Fig. 7 of the drawings. When the pump is set in motion, the centrifugal force exerted on the arm B by its rotation with the pipe P swings said arm from its perpendicular position toward a horizontal position, as indicated by dotted lines in Fig. 7 of the drawings, and this 'movement of the arm R carries the solid upper end of said arm across the channel o of the nipple, and thus closes the same. So soon as the motion of the pump isstopped,the arm R drops down into its normal perpendicular position, in coincidence with the channel o, and allows water to escape from that portion of the discharge-pipe which is above the nipple.
